The power driving new energy vehicles comes from hundreds of lithium battery cells. In the manufacturing process of lithium batteries or battery packs, more than 20 processes require welding to achieve conductive connections or sealing. The quality of welding is crucial for the safety performance of the entire vehicle.
Laser welding, a significant non-contact welding method, uses a high-energy laser beam focused on the product surface or inside to achieve atomic bonding between two separate products. Compared to traditional argon arc welding, resistance welding, and ultrasonic welding, laser welding has notable advantages: small heat-affected zone, non-contact processing, and high processing efficiency.
